## AsyncTemplate

```python
class AsyncTemplate(TemplateBase)
```

Asynchronous template builder for E2B sandboxes.


### build

```python
@staticmethod
async def build(template: TemplateClass,
                alias: str,
                cpu_count: int = 2,
                memory_mb: int = 1024,
                skip_cache: bool = False,
                on_build_logs: Optional[Callable[[LogEntry], None]] = None,
                api_key: Optional[str] = None,
                domain: Optional[str] = None) -> BuildInfo
```

Build and deploy a template to E2B infrastructure.

**Arguments**:

- `template`: The template to build
- `alias`: Alias name for the template
- `cpu_count`: Number of CPUs allocated to the sandbox
- `memory_mb`: Amount of memory in MB allocated to the sandbox
- `skip_cache`: If True, forces a complete rebuild ignoring cache
- `on_build_logs`: Callback function to receive build logs during the build process
- `api_key`: E2B API key for authentication
- `domain`: Domain of the E2B API
Example
```python
from e2b import AsyncTemplate

template = (
    AsyncTemplate()
    .from_python_image('3')
    .copy('requirements.txt', '/home/user/')
    .run_cmd('pip install -r /home/user/requirements.txt')
)

await AsyncTemplate.build(
    template,
    alias='my-python-env',
    cpu_count=2,
    memory_mb=1024
)
```


### build\_in\_background

```python
@staticmethod
async def build_in_background(template: TemplateClass,
                              alias: str,
                              cpu_count: int = 2,
                              memory_mb: int = 1024,
                              skip_cache: bool = False,
                              on_build_logs: Optional[Callable[[LogEntry],
                                                               None]] = None,
                              api_key: Optional[str] = None,
                              domain: Optional[str] = None) -> BuildInfo
```

Build and deploy a template to E2B infrastructure without waiting for completion.

**Arguments**:

- `template`: The template to build
- `alias`: Alias name for the template
- `cpu_count`: Number of CPUs allocated to the sandbox
- `memory_mb`: Amount of memory in MB allocated to the sandbox
- `skip_cache`: If True, forces a complete rebuild ignoring cache
- `api_key`: E2B API key for authentication
- `domain`: Domain of the E2B API

**Returns**:

BuildInfo containing the template ID and build ID
Example
```python
from e2b import AsyncTemplate

template = (
    AsyncTemplate()
    .from_python_image('3')
    .run_cmd('echo "test"')
    .set_start_cmd('echo "Hello"', 'sleep 1')
)

build_info = await AsyncTemplate.build_in_background(
    template,
    alias='my-python-env',
    cpu_count=2,
    memory_mb=1024
)
```


### get\_build\_status

```python
@staticmethod
async def get_build_status(build_info: BuildInfo,
                           logs_offset: int = 0,
                           api_key: Optional[str] = None,
                           domain: Optional[str] = None)
```

Get the status of a build.

**Arguments**:

- `build_info`: Build identifiers returned from build_in_background
- `logs_offset`: Offset for fetching logs
- `api_key`: E2B API key for authentication
- `domain`: Domain of the E2B API

**Returns**:

TemplateBuild containing the build status and logs
Example
```python
from e2b import AsyncTemplate

build_info = await AsyncTemplate.build_in_background(template, alias='my-template')
status = await AsyncTemplate.get_build_status(build_info, logs_offset=0)
```
